“…It is A second comparison of simulated mass attenuation coefficients toward the EPICS2017-based interpolations is shown in Tables 6 and 7, for several gamma ray energies using the simulation toolkit Geant4. Table 6 shows the mass attenuation coefficients using the Li 2 O-B 2 O 3 -P 2 O 5 -TeO 2 glass systems from Aşkın et al 2019 [29], while Table 7 shows evaluations for B 2 O 3 -Bi 2 O 3 -PbO-TiO 2 from Sayyed et al 2019 [30], taken for several discrete gamma energies. These results show comparable agreement between both methods.…”

In this paper, the investigation of the Electron–Photon Interaction Cross Sections 2017 (EPICS2017) library on the shielding characteristics of several glasses under various chemical systems is presented. The EPICS2017 library of ENDF/B-VIII was interpolated to calculate the mass attenuation coefficients (MACs) of selected glass systems. Results from EPICS2017 have been compared with values from experimental and theoretical methods used to evaluate the photon shielding properties. The EPICS2017 estimations strongly agreed with experimental MAC results. The MAC values from several Monte Carlo codes (Geant4, MCNP4C, MCNP5, and FLUKA) based on EPDL97 or EPDL89 strongly agreed with EPICS2017-based interpolation, within reasonable deviations. The obtained results indicate that EPICS2017 can be used to evaluate the MACs for any glass system in which there are no experimental values available at various photon energies. It was demonstrated that the linear EPICS2017 library can be a considerable tool in future photon shielding research and developments of glass systems, as a recent alternative to the widely used XCOM by NIST.

“…It indicates that the chosen glasses have a higher radiation shield strength at lower energy. The present glasses were compared to different glass types [38][39][40] and concrete [39] to photon attenuation capabilities [39]. Relation [38][39][40] shows the mean free paths of prepared glasses (TSH1, TSH2, TSH3) below LIBTe40 and RS-253-G18 (see Fig.…”

The gamma radiation protection parameter for the TeO2-LINbO3-BaF2-La2O3 network modified by Nb2O5/TiO2 in the present work. The following compounds have been examined: [77.53TeO2-7.31LiNbO3-4.16Nb2O5-10% BaF2-1.0La2O3, sample code TSH1), [71.69TeO2-7.31LiNbO3-10BaF2-1.0La2O3, sample TSH2] and [76.69TeO2-7.31LiNbO3- 5TiO2-10BaF2-1% La2O3 and sample code TSH3]. Within this, we specify the criteria for shielding such as mass attenuation coefficients (μm/), effective atomic numbers (Zeff), electron density (Ne), half-value layers (HVL), mean free path (MFP). The TSH3 glasses have a greater gamma-ray safety performance because of a higher value of HVL, (μm/), and MFP. The observed glasses display good gamma ray safety compared to used standard radiation-shielding materials, namely RS-360, and RS-520. Finally, the structure of these glasses investigates at wavenumber in the range 50 to 1200 cm-1 by using Raman spectra.

“…Investigations on γ-ray shielding ability of PbO-B2O3-TeO2-P2O5 glasses revealed that these glasses are more effective than regular concrete in blocking gamma radiation [14]. The γ-ray shielding capacity of lithium-boro-phospho-tellurite glasses has been estimated using Geant4 and Fluka codes [21]. The highest numbers of photons that can pass through the glass were found to be at 1330 keV of photo energy.…”

This article presents investigated results on physical, electrical and gamma radiation shielding properties of glasses of composition, (P2O5)0.25-(TeO2)0.5-x-(Na2O)0.1- (ZnO)0.15-(CoO)x (x= 0.10, 0.15, 0.20, 0.25, 030 and 0.35) were synthesized by melt quenching procedure. After confirming non-crystallinity, density was measured and found it to be decreased with increase of CoO concentration in the range 4.0370 gm/cm3 - 3.5673 gm/cm3. Molar volume, mean distance between TMIs, small polaron radius, oxygen packing density and field strength were estimated. Conductivity was measured in the temperature range 303K -663K. High temperature conductivity is found to be varied as per Mott’s (SPH) model. High temperature activation energy is found to be increased with CoO content. Low temperature conductivity variation has been analyzed using Mott’s (VRH) model. Gamma ray shielding parameters were evaluated using Phy-X/PSD software for the energy range 0.005 MeV-15 MeV. The mass and linear attenuation coefficients were found to decrease with CoO content and photon energy. Half and tenth value layers increased with increase of mole fractions of CoO. All the observed shielding parameters are superior to those reported previously for other glasses. The glass with x=0.10 is best suited for the utility of gamma shielding at low energy.
